“wo hanatsu / wo hassuru” Meaning — Give Off / Emit (light, scent…) [JLPT N1]

Content by NTJ Kuma · Nihongo to Japan editorial team · Updated July 27, 2026

“Stand out brilliantly,” “give off a scent” — emitting light, smell, or presence, formal, with examples. (JLPT N1)

「異彩を放つ」「香りを発する」 — giving off light, emitting fragrance

To depict something giving off light, fragrance, an aura, literature and criticism use an elegant, forceful pair of verbs — 「その作品は、他とは違う異彩を放っていた (that work gave off a brilliance unlike any other).」 「〜を放つ／〜を発する」 = give off, emit (light, fragrance, sound, aura). This guide clarifies its core of “giving off outward,” specially warns that 「放」 isn't “to place” and 「発する」 is unrelated to 「出発,」 and separates it from the intransitive 「が漂う.」

Core: give off, emit outward (light, fragrance, sound, aura, charm)

「noun ＋ を放つ／を発する」 means “(something) gives off, emits ～ outward (light, fragrance, sound, aura, charm)”:

• ダイヤモンドが、まばゆい輝きを放つ (a diamond gives off a dazzling brilliance).
• 彼は、周囲を圧倒する存在感を放っていた (he gave off a presence that overwhelmed those around).
• その花は、甘い香りを発している (that flower gives off a sweet fragrance).
• 危険を知らせる警報が、鋭い音を発した (the danger alarm emitted a sharp sound).

Feel: both are transitive verbs (with 「を」) for “giving off, emitting outward,” depicting something releasing light, fragrance, sound, aura, charm: a work giving off charm, a diamond giving off brilliance, a rose giving off fragrance, a person giving off an aura (異彩を放つ). It's more elegant, forceful than the colloquial 「出す,」 mostly for depiction, criticism, literature. Subtly: 「放つ」 stresses giving off strongly (light, aura, brilliance), 「発する」 more neutrally means emit (sound, light, message). In English: give off, emit, radiate.

⚠️ Common mistakes to avoid

① ⭐「放」 isn't “to place”! 「を放つ」 = to release, shoot outward, not “put at ～.” This is Chinese speakers' most typical misreading. Chinese “放” often means “place, put down” (like “put on the table”), but Japanese 「〜を放つ」 specifically means “release, shoot, give off outward” (give off light, fragrance, aura), not “place”! So you can't say 「本を放つ」 for “put the book on the table” (✗本を放つ → ○本を置く). 「放つ」 means “release, emit, shoot (outward)” — 光を放つ (give off light), 矢を放つ (shoot an arrow), 犬を放つ (let the dog out). Test: 「を放つ」 = give off／release／shoot outward (light／fragrance／aura); “place, put down” → use 「置く.」 Don't read 「放つ」's 「放」 as the Chinese “place.”

② ⭐「発する」 is unrelated to 「出発」! They just share the kanji 「発.」 This is another look-alike misunderstanding. Because 「発」 also appears in 「出発（しゅっぱつ）」 (departure), Chinese speakers easily think 「発する」 relates to “departing, starting.” But 「〜を発する」 means “emit (sound, light, signal, message, heat),” entirely unrelated to “departure,” the two just sharing the kanji 「発」: 音を発する (emit a sound), 光を発する (emit light), 言葉を発する (utter words), 警報を発する (issue an alarm). Test: 「〜を発する」 = emit (sound／light／message／heat), unrelated to “departing, starting” (just sharing 「発」).

③ It's a written, literary expression, more elegant and forceful than the colloquial 「出す.」 This is the register point. 「を放つ／を発する」 are both written, literary expressions, with flavor and force, mostly for depiction, criticism, literature (a work giving off charm, a diamond giving off brilliance, a person giving off an aura). For colloquial “give off, emit,” 「出す」 is more common (光を出す, 匂いを出す) — but 「出す」 is plainer, without flavor. So 「異彩を放つ」「香りを発する」 are far more elegant, forceful than 「光を出す」「匂いを出す.」 Test: to depict in writing, literarily “give off／emit (light／fragrance／aura)” → を放つ／を発する (elegant); for colloquial → 出す (plain).

④ Separate it from 「が漂う」 — を放つ／発する are transitive (something actively gives off), が漂う is intransitive (～ wafts). Both relate to fragrance, atmosphere, but one is transitive, one intransitive. 「(noun) を放つ／を発する」 = (something) gives off ～ (transitive, with を, the subject is the source giving off): 花が香りを放つ (the flower gives off fragrance — subject “flower” actively releases “fragrance”). It stresses “something (actively) gives off something outward.” 「(noun) が漂う」 = ～ wafts, drifts (intransitive, with が, the subject is the wafting thing itself): 甘い香りが漂う (a sweet fragrance wafts — subject “fragrance” drifts in the space by itself). It stresses “something (by itself) wafts, drifts in space.” Difference: 「を放つ／発する」 = transitive (something gives off ～, source ＋ を ＋ the given-off thing); 「が漂う」 = intransitive (～ wafts, drifts, the drifting thing ＋ が). Test: to say “(something) gives off (fragrance／light)” (source actively releases) → を放つ／を発する; to say “(fragrance／atmosphere) wafts, drifts” (the thing drifts by itself) → が漂う. So “the flower gives off fragrance” uses 「花が香りを放つ,」 “fragrance wafts” uses 「香りが漂う.」

💡 Learning tip

「〜を放つ／〜を発する」 = give off, emit (light, fragrance, sound, aura) — three points: ①⭐「放」 isn't “to place” — を放つ = give off／release／shoot outward (light／fragrance／aura), not “put at ～” (placing uses 「置く」); ②⭐「発する」 is unrelated to 「出発」 — を発する = emit (sound／light／message／heat), just sharing the kanji 「発」; ③ it's a written, literary expression (more elegant, forceful than the colloquial 「出す」), separate it from the intransitive 「が漂う.」 This pair is a weapon of depiction, criticism, literature — 「異彩を放つ」「凄みを放つ」「香りを発する」 render, elegantly and vividly, that clarity and force of “something giving off light, an aura, fragrance.” To elegantly depict “give off, emit,” 「を放つ／を発する」 has far more flavor than the plain 「出す.」

❓ Common questions

Q: Can 「本を放つ」 mean “put the book on the table”?

No! 「放つ」 isn't “to place” — this is Chinese speakers' most typical misuse. Chinese “放” often means “place, put down” (put on the table, put down one's hand), but Japanese 「放つ（はなつ）」 means something entirely different — “release, give off, shoot, let loose outward”: 光を放つ (give off light), 香りを放つ (give off fragrance), 異彩を放つ (give off brilliance), 矢を放つ (shoot an arrow), 犬を放つ (let the dog out to run). It stresses “releasing, shooting, giving (something) off outward,” entirely unlike the Chinese “put at ～ (place).” So “put the book on the table” uses 「置く」 — 本を机の上に置く (○), not 「本を放つ」 (✗, which would become a strange “shoot／fling the book out”). Test: “place, put down” (at somewhere) → 置く (本を置く, 荷物を置く); “give off／release／shoot outward” → 放つ (光を放つ, 香りを放つ, 矢を放つ). Don't equate Japanese 「放つ」 with the Chinese “place.”

Q: Is the 「発する」 of 「音を発する」 related to 「出発」 (departure)?

No! 「発する」 and 「出発」 just share the kanji 「発」; their meanings are entirely different. Because 「発」 also appears in 「出発（しゅっぱつ）」 (departure), 「発車」 (departing a vehicle), Chinese speakers easily think 「発する」 relates to “departing, starting, setting off.” But 「〜を発する（はっする）」 means “emit (sound, light, heat, signal, message, words)” — 音を発する (emit a sound), 光を発する (emit light), 熱を発する (give off heat), 警報を発する (issue an alarm), 言葉を発する (utter words, speak up). It's entirely unrelated to “departing, setting off,” the two just happening to both use the kanji 「発」 (「発」 itself has several meanings: emit, shoot, occur). So 「音を発する」 is “emit a sound,” not “the sound departs.” Test: 「〜を発する」 = emit (sound／light／heat／message／words), read as “giving something off outward,” unrelated to “departing, starting.” It's a look-alike-kanji misunderstanding — remember “発する = emit” and you won't confuse them.
